Associate Professor, Associate Department Head


Research in my group will use organic synthesis, combinatorial methods, and analytical techniques, such as tandem liquid chromatography-mass spectrometry and nuclear magnetic resonance, to answer biologically relevant questions at the molecular level. We have also established collaborations with a number of other researchers, both at UTK and at other universities, and these interactions have enhanced our ability to explore the underlying chemical component of a variety of biological processes. The figure below gives an overview of the research in our laboratory, and more detailed descriptions of the projects will be posted soon.

Campagna Research


Dr. Campagna completed his B.S. in Chemistry at North Carolina State University in 2000 and conducted research with Prof. Jonathan S. Lindsey on the chemical synthesis of bacterial chromosomes. He received his Ph.D. from Princeton University in 2006, after working with Prof. Martin F. Semmelhack on a joint project with Profs. Bonnie L. Bassler and Frederick M. Hughson to characterize the chemical properties of an inter-species bacterial signaling molecule, autoinducer-2. Dr. Campagna then performed post-doctoral fellow research with Prof. Joshua D. Rabinowitz at the Lewis-Sigler Institute for Integrative Genomics at Princeton University where he developed mass spectrometric methods for the identification of novel biochemical pathways and natural products from whole cell extracts. He joined the Chemistry Department at UT Knoxville in August 2007.
